We begin as the family gather for the funeral in January, and end on New Year's Eve as the story takes us through Cathy's minor and major life events throughout the year.
It's a day of great emotion as we first meet Cathy on the morning of her husband's funeral. Battling her brother's partner and meeting her son's new and over-enthusiastic girlfriend Kelly, Cathy prepares herself for the day, with a little help from her friend, Michael.
